I would say A. Because c and d r very dangerous if u think about it. And b is right in some situations. But if u do a then people can see whts going on if something happened because of the light. and it is safe. If wrong let me know. :D
It depends if you want to land harder or lighter. A front handspring step out is a softer landing because your weight is distributed while a front handspring has you landing on two feet. I have been doing gymnastics for 12 years and let me tell you that a front handspring step out should be easier to do and does not hurt as bad. =)
